我找不到在 cloud9.io 中设置 gulp browsersync 的说明。我认为 browsersync 的设置 ip 和 host 是错误的。我尝试在我的 gulpfile.coffee 中这样做：

require('coffee-script/register')
gulp = require('gulp')
$ = require('gulp-load-plugins')()
browserSync = require('browser-sync')

gulp.task 'sass', ->
    return gulp.src(['./sass/**/*.sass'])
        .pipe($.sourcemaps.init())
        .pipe($.sass({
            indentedSyntax: true,
            errLogToConsole: true,
            outputStyle: 'compressed'
        }))
        # .pipe($.autoprefixer('last 3 version'))
        .pipe($.sourcemaps.write('.'))
        .pipe(gulp.dest('./css'))

gulp.task 'stylus', ->
  gulp.src('./stylus/**/*.styl')
    .pipe($.sourcemaps.init())
    .pipe($.stylus())
    .pipe($.sourcemaps.write('.'))
    .pipe(gulp.dest('./css'))

gulp.task 'server', ->
    browserSync({
        server: {
            baseDir: "./",
            port: process.env.PORT,
            host: process.env.IP  
        },
        browser: "google chrome"
    })

gulp.task 'watch', ->
    gulp.watch(['./sass/**/*.sass'], ['sass'])
    gulp.watch(['./stylus/**/*.styl'], ['stylus'])

gulp.task 'default', ['server', 'sass', 'stylus', 'watch']

当我运行命令'gulp'时：

suenot@car:~/workspace $ gulp
[17:20:06] Requiring external module coffee-script/register
[17:20:10] Using gulpfile ~/workspace/gulpfile.coffee

我做错了什么？请帮助并为我糟糕的英语感到抱歉。

Cloud9.io 尝试打开browser: "google chrome". 我从服务器对象中删除了这个字符串并传输端口和主机参数，然后 gulp 开始成功。

gulp.task 'server', ->
browserSync({
    server: {
        baseDir: './'
    },
    port: process.env.PORT,
    host: process.env.IP
})
